Powered by GoogleBathrooms are filthy, charge you to get in, waiting in line behind a disabled couple who couldn’t get a golf cart, snack shack is slow and terrible… money grab for youth sports at its finest. Oh and they have house teams and the umps are on payroll….
Attended the memorial weekend tournament with my son and his team. The place was extremely nice. So many fields. Different vendors. Staff was very helpful and kind. Food (breakfast and lunch) and drinks were great. All turf field. Had all kinds of travel teams from around the states and different ages. Batting cages were available as well. Had flying balls at all times but they had net protection ls everywhere. Bathrooms were clean 👌🏻
This place is a total ripoff. They make you pay $10 per person per day to watch your kid play baseball. Total ripoff. Do not recommend at all.
The property seemed well maintained. Basically a bunch of teenagers running the place. We paid $40 for two days to watch our son play. Add that to the tournament fees the organizations paid I expected much more. First of all, the concession stand prices are outrageous. Especially since the food is disgusting. Some of the concession stand workers are extremely rude. Secondly, and honestly the biggest complaint was the umpires. Explain to me how this venue charges so much for admission, tournament fees and concessions yet are employing umpires that don’t know the rules and allowed coaches to walk all over them. I’m pretty sure I witnessed an intoxicated umpire, upping a game. Lastly, to save grace, and the reputation of Diamond Nation I highly suggest the owners/organizers have a better look at what they are allowing go on at their venue. Otherwise, I do believe you’ll see a decline in sign ups for the tournaments that were once thought of as competition. Training umpires should be your first priority. Especially when it comes to young kids. Umpires need to stop allowing coaches to mentally break down kids of opposing teams. Shame on the coaches who strategically chose to do this for the win.
Fields are nice. Odd fence length for 50/70. The didtance is 200ft but should be 250. For what you pay, the fields should be more versatile and have fences you can clear instead of where balls just roll to infinity or fences that match the age group. However, the place is beautiful and has everything you need. Great food, protective nets over-head, and clean bathrooms. Parking isnt great.
